States of Matter

The different forms that matter can exist in, including solid, liquid, gas, and plasma.

Solid

A state of matter with a definite shape and volume. Particles are tightly packed and vibrate in place.

Liquid

A state of matter with a definite volume but an indefinite shape; particles are close together but can move around each other.

Gas

A state of matter with neither a definite shape nor a definite volume; particles are far apart and move freely.

Study Notes

States of Matter

  • Matter exists in four states: solid, liquid, gas, and plasma.
  • These states are determined by particle arrangement, energy, and distance between particles.

Solids

  • Solid particles are tightly packed, vibrating around fixed positions.
  • Solids have a definite shape and volume.

Liquids

  • Liquid particles are tightly packed, but mobile enough to slide past each other.
  • Liquids have a definite volume but an indefinite shape.

Gases

  • Gas particles are widely spaced and move freely.
  • Gases have an indefinite shape and volume.

Plasma

  • Plasma is an ionized gas.
  • Plasma is an excellent conductor of electricity and affected by magnetic fields.
  • Plasma, like gases, has an indefinite shape and volume.

Kinetic Theory of Matter

  • Matter consists of particles in continuous, random motion.

Characteristics of Gases

  • Gases assume the volume and shape of their containers.
  • Gases completely mix when in the same container.
  • Gases have much lower densities than liquids and solids.
  • Gases are highly compressible; volume decreases with increasing pressure.

Temperature

  • Absolute temperature (Kelvin) should be used when dealing with gases.
  • °C = ( °F - 32 ) / 9
  • K = °C + 273

Pressure

  • Barometers measure atmospheric pressure.
  • Manometers measure contained gas pressure.
  • Key units at sea level include:
    • 101.325 kPa (kilopascal)
    • 1 atm
    • 760 mm Hg
    • 760 torr
    • 14.7 psi
  • Pressure is force per unit area (N/m²).

STP (Standard Temperature and Pressure)

  • Standard temperature is 0°C (273 K).
  • Standard pressure is 1 atm (101.325 kPa).

Gas Laws

  • Boyle's Law: Pressure and volume are inversely related at constant temperature (P₁V₁ = P₂V₂).
  • Charles' Law: Volume and absolute temperature are directly related at constant pressure (V₁/T₁ = V₂/T₂).
  • Avogadro's Law: Volume and number of moles are directly related at constant pressure and temperature (V₁/n₁ = V₂/n₂).
  • Gay-Lussac's Law: Pressure and absolute temperature are directly related at constant volume (P₁/T₁ = P₂/T₂).
  • Combined Gas Law: Relates pressure, volume, temperature, and amount of a gas (P₁V₁/T₁n₁ = P₂V₂/T₂n₂).

Gas Law Problems

  • Examples of applying gas laws to solve problems involving changes in pressure, volume, temperature, and number of moles are provided. These calculations follow the respective gas law formulas.
